Abstract
N-acetylmannosamine dehydrogenase gene derived from a microorganism belonging to the genus Flavobacterium, e.g., Flavobacterium sp. No. 141-8 strain and defined by a specific restriction enzyme map which encodes 271 amino acid sequence. Using the recombinant DNA, N-acetylmannosamine dehydrogenase can be produced in a simpler manner in an industrial scale. The enzyme is useful for quantitative determination of sialic acid.
